Book Description
We report branching fraction measurements for exclusive decays of charged and neutral B mesons into two-body final states containing a charmonium meson. We use a sample of 22.72[+-] 0.36 million B[bar B] events collected between October 1999 and October 2000 with the BABAR detector at the PEP-II storage rings at the Stanford Linear Accelerator Center. The charmonium mesons considered here are J/[psi], [psi](2S), [chi][sub c1], and the light meson in the decay is either a K, K*, or[pi][sup 0].

Book Description
The authors report preliminary results on the measurement of branching fractions of exclusive decays of neutral and charged B mesons into two-body final states containing a charmonium state and a light strange meson. The charmonium mesons considered are J/[psi], [psi](2S) and [chi]{sub c1}, and the light mesons are either K or K*. They use a sample of about 124 million B{bar B} events collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center.

Book Description
We report measurements of branching fractions and charge asymmetries of exclusive decays of neutral and charged B mesons into two-body final states containing a charmonium state and a light strange meson. The charmonium mesons considered are J/[psi], [psi](2S) and [chi]{sub c1} and the light meson is either K or K*. We use a sample of about 124 million B{bar B} pairs collected with the BABAR detector at the PEP-II storage ring at the Stanford Linear Accelerator Center.

Book Description
We report on exclusive decays of B mesons into final states containing charmonium using data collected with the BABAR detector at the PEP-II storage rings. The charmonium states considered here are J/[psi], [psi](2S), and [chi]{sub c1}. Branching fractions for several exclusive final states, a measurement of the decay amplitudes for the B° 2!J/[psi] K* decay, and measurements of the B° and B masses are presented. All of the results we present here are preliminary.

Book Description
This thesis, which won one of the six 2015 ATLAS Thesis Awards, concerns the study of the charmonium and bottomonium bound heavy quark bound states. The first section of the thesis describes the observation of a candidate for the chi_b(3P) bottomonium states. This represented the first observation of a new particle at the LHC and its existence was subsequently confirmed by D0 and LHCb experiments. The second part of the thesis presents measurements of the prompt and non-prompt production of the chi_c1 and chi_c2 charmonium states in proton-proton collisions. These measurements are compared to several theoretical predictions and can be used to inform the development of theoretical models of quarkonium production.

Book Description
This book offers the first strong evidence of the existence of CP violation in neutral B decays extracted from sophisticated B factories in the US and Japan. It also holds out the expectation of rare B decays and D, K physics in the near future. In addition, new physics beyond the Standard Model is described. Both experimental and theoretical points of view are given.

Book Description
The authors reconstruct the charmonium mesons J/[psi], [psi](2S) and[chi][sub c] using a sample of 8.46 x 10[sup 6] B[bar B] events collected by the BABAR detector operating at e[sup+]e[sup -] center of mass energies near the[Lambda](4S) resonance. by measuring rates relative to the branching fraction of the J/[psi], they obtain preliminary inclusive B branching fractions of (0.25[+-] 0.02[+-] 0.02)% to the[psi](2S) and (0.39[+-] 0.04[+-] 0.04)% to the[chi][sub c1], and set a 90% confidence level limit of 0.24% on decays through the[chi][sub c2].

Book Description
This volume contains many excellent articles presenting the most recent progress in high energy physics and the current interesting problems concerning flavor physics. The reader will see how flavor physics has become a central area of particle physics, with the Standard Model (SM) being subjected to increasingly precise experiments, and why the remaining puzzles in the SM, such as the mechanisms of symmetry breaking and CP violation, as well as fermion mass and mixing generation, all are mysteries hidden in the physics of flavor. The book also shows that flavor physics is likely to be a window for probing new physics beyond the SM for many years to come.
